Detailed Answer
Multiple bridge crane remotes in the same area have a cross-interference risk; prevention relies on: 1. Independent pairing (unique code per set); 2. FHSS frequency hopping (Leader, different hop sequences); 3. Multi-channel division (433/470MHz multiple channels). Dozens of devices in one area (large workshops/ports) can operate without interference. If interference appears, check whether pairing is independent and channels conflict.
| Pairing | Independent & unique |
| FHSS | Hop-sequence isolation |
| Channel | Division |
Note:Always pair new remotes independently to prevent miscontrol.
